This looks like a redo of an older Hubble Space Telescope image; but, why not?

Here's an article argueing that quantum entanglement exists without a shadow of a doubt. Link here --> Quantum ‘spookiness’ passes toughest test yet

And someone recently unearthed this great video documentary on "Quantum Spookiness."

General/Special Relativity and Quantum Mechanics brought up questions about the nature of science - causality and whether we can predict everything.  Before then, Mathematics had raised questions about knowledge in the discovery of non-Euclidean geometries, and then abstract algebras, quaternions and so on.  In 1931, Kurt Gödel published his inconsistency/incompleteness theorems.  Jacob Bronowski's "Origins of Knowledge and Imagination" in my opinion perhaps, unifies and explains all these problems.  See my Origins of and Nature of Mathematical Knowledge post, third post of this blog for an introduction to these ideas.
